. IMPROVEMENT IN STOVE-DAMPERS.

Specification forming part of Letters Patent No. 144,676, dated November 18, 1873; application filed June 24, 1873.

To all whom it may concern:

Be it known that I, HosEA H. HUNTLEY,

-of the city of Quincy, Illinois, have invented certain new and useful Improvements in Stove- Dampers, of which the following is a speci- 1 fication, reference being had to the accompanyarrangement, and furnished with plates having diagonal slots, in which work the ends of the guide-rods attached to swinging dampers, so that by operating the rod the dampers are opened or closed, or held at any desired angle.

Figure l is a plan view of a stove with a device embodying the elements of the invention applied thereto. Fig. 2 is a vert-ical central section of same. Fig. 3 is a detached view of a device embodying the elements of the invention. .i

In the present instance, the invention is applied to a cooking-stove, so arranged that when the dampers are opened the products of combustion shall come in contact with the outer surface of the lining of a reservoir secured to the upper part of the rear of the stove, though it is obvious that the device may be applied to stoves of almost every construction.

In the accompanying drawings, A is a damper-rod, passing horizontally through apertures in the wall of the stove B and the iiue C, the rod thus being allowed to move and arrangement, the flue C, adjacent to the point :through which the rod A passes, being cut out so as to allow the plates F to move as the rod is operated. Thedampers I are hinged to the flue C, one on the inner and one on the outer surface thereof, in such manner as to swing in the same direction7 and when closed to cover the apertures L in the flue. To the corresponding upper portions of the dampers I are secured the guide studs or standards M, the upper extremities of which` protrude through the slots H in the plates F, so that as the rod A is moved the dampers I are operated.

By forcing the rod A inward, those portions of theplates F adjacent one side of the slots H come in Contact with the guide studs or standards M, causing the dampers I to swing upon their hinges until they come in conta-ct with those portions of the iiue C adjacent the apertures L, which are thus closed, whereby the products of combustion are forced tlnough v the vertical and horizontal heat or draft passages. By a contrary movement of the rod A the dampers I are opened, when the ame and heat, descending the side iiues O, pass' through the apertures L in the ue G, coming directly in contact with the surface of the lining of the reservoir N.

It is obvious that as the rod A is drawn out or forced inward, the dampers I are respectively and proportionately opened or closed; and also that they will retain their relative position when the movement of the rod Ais determined.

What I claim as my invention, and desire Witnesses SAM. R. EivrERY, Jr., C. P. WrNcHEsTEn.
